Enables us to guarantee that we followed the regulations
The ability to query everything that's in Microsoft and send links or add people, like managers, to review the documents is valuable. It's easy as I don't have to download and email anything. I just add them as a reviewer, and they can access it from there. Purview's inclusion of critical regulations is essential. Lawyers will ask how we gathered information. With Purview, we can guarantee that we've followed the regulations. The visibility into what's happening and who has access is great for legal matters and saves us a lot of time.
